How to setup a maven project in Intellij IDEA 12

Question

I have problem importing a maven project which was created by Netbeans into the IDEA 12. The dependency artifacts writen in the pom doesn't work. It told me that "cannot resolve symbol 'springframework'" on "import org.springframework.xxx;". When I runs it, it says that org.springframework.xxx doesn't exist. Here is the pom file

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer 1

When the pom.xml file is available in your project, you can generate the files needed by IntelliJ idea project by running this command:

mvn idea:idea

Check out more options and details here: http://maven.apache.org/plugins/maven-idea-plugin/usage.html

Answer 2

If the project runs on the command line (mvn clean install) the chance is like 100% it will work in IntelliJ 12 too :-)

After File -> Project Import -> From external Maven Model you should see the modules.

What I would check in the IntelliJ settings is the location of the maven home directory (File -> Settings -> Maven) and the settings.xml files it reads (or does not read).

The mvn install within the IDE should not differ from what happens on the command line. If it does it would compare mvn help:effective-settings output from the command line and from IntelliJ (maybe also from Netbeans).

If you just dont see all modules right click on the parent-pom.xml and choose maven -> reimport. To resolve the dependencies you have to execute an install once. It does not automatically resolve dependencies in all cases.
